I owned one of those, my first real welder. Mine had capacitors (power factor correction) to reduce the primary power requirements and also a reduced output from the one you mentioned. It still managed to fry incoming power lines as I noted in another post. They require lot's of line power compared to that of todays technology (e.g.: inverters). You'll need serious line power to run it at the rated output. Close to 100 amps if I remember.

If it is in good shape and the $ is right, I'm sure you can still get parts for them. Lot's of people still own them, that's good marketing right there.
